Year 11 Waves - Check your Understanding

Radio waves are received at a house at the bottom of a hill.
The waves reach the house because the hill has caused them to be 

• diffracted.
• radiated.
• reflected.
• refracted.

Which is the best description of the speed of a water wave? 

•  the distance between one wave crest and the next
• the distance between the crest of a wave and a trough
•  the distance that a particle of water moves up and down in one second
• the distance that a wavefront moves along the surface in one second
